摘　　要：研究株洲清水塘区土壤纵面重金属的分布特征。结果表明,该地区锌、铜、铅、镉、砷、铷、钴、镍、铬、汞等重金属含量平均值均高于全国土壤元素背景值。锌、铅、镉、砷等元素平均含量明显偏高。大多数重金属含量随土层的加深呈下降趋势,土壤各层重金属变异系数波动范围较大,位于冶炼厂附近的土壤剖面采样点,重金属含量平均值明显高于其他采样点。土壤中的锌和铜、铅和锌、锌和汞、铅和汞、铷和镉有正相关关系(p<0.01),铜和锶、铅和锑、锶和铬之间具有一定的负相关关系。The heavy metals distribution feature of the soil profile in Qingshuitang Zhuzhou is investigated. The results indicate that the average content of Zn,Cu,Pb,Cd,As,Rb,Co,Ni,Cr and Hg in Qingshuitang is all higher than the soil element background values in China. Element content of Zn,Pb,Cd and As is obviously on the high side. Most heavy metals content is in decreasing trend with the soil depth increasing,the varying range of soil heavy metals variation coefficient in each layer is much great,and the heavy metal content in average near the smelters is significantly higher than the other sampling points. The average content of Zn-Cu,Pb-Zn,Zn-Hg,Pb-Hg and Rb-Cd takes on positive correlation（ p〈0. 01）,and the average content of Cu-Sr,Pb-Sb and Sr-Cr in soil presents a negative correlation.
